Doctor Advances Cryopreservation in Heart Regeneration and Organ Transplantation

At Harvard Medical School and Massachusetts General Hospital, Dr. Rasha Al-attar’s research is at the forefront of advancing heart regeneration and organ transplantation. Initially focusing on stem cell-derived cardiomyocyte (hPSC-CM) transplantation to repair infarcted heart tissue, Dr. Al-attar faced a significant challenge: while immature hPSC-CMs survive freezing, they often induce...

Pressure Increase Method Marks Significant Advancement in Cryogenic Controls and Safety

Ensuring the integrity of packaging in cryogenic environments is crucial for maintaining product quality and operational safety. Recent advancements in non-destructive leak testing technology underscore significant improvements in cryogenic controls and safety by emphasizing the need for precise and reliable testing methods. Effective leak detection is essential for preserving the...

Tests Show High Temperature Superconducting Magnets Ready for Fusion

In the early hours of September 5, 2021, engineers at MIT’s Plasma Science and Fusion Center (PSFC) achieved a groundbreaking milestone by demonstrating a world-record magnetic field strength of 20 tesla with a new high-temperature superconducting magnet. This breakthrough is crucial for advancing fusion power technology, with the potential to...

How Hydrogen Fuel Cells and Combustion Could Revolutionize Racing

Hydrogen power is gradually making its mark on the motorsport scene. This year, we have already witnessed hydrogen race cars competing in the Fuji 24 Hours, hillclimbs, and the Dakar Rally. Looking ahead to 2025, the world’s first hydrogen championship, Extreme H, will debut, and by 2027, hydrogen prototypes are...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...
